"The DNA repair protein yKu80 regulates the function of recombination enhancer during yeast mating type switching."

Ruan C, Workman JL, Simpson RT

Abstract:
Recombination enhancer (RE) is essential for regulating donor preference during yeast mating type switching. In this study, by using minichromosome affinity purification (MAP) and mass spectrometry, we found that yeast Ku80p is associated with RE in MATa cells. Chromatin immunoprecipitation assays confirmed its occupancy in vivo. Deletion of YKU80 results in altered chromatin structure in the RE region and more importantly causes a dramatic decrease of HML usage in MATa cells. We also detect directional movement of yKu80p from the RE towards HML during switching. These results indicate a novel function of yeast Ku80p in regulating mating type switching.
